The next configuration step is teaching the environmental conditions (teach).
8.2
Teaching the environmental conditions
During teaching, the system checks whether the signals of all beams are within a certain corridor.
This means that a teach event generally regulates all beams to the preset function reserve (or sensitivity)
for the current operating range. This ensures that all beams exhibit an identical switching behavior.
Prerequisites:
• The light curtain must be correctly aligned (see chapter 8.1).
You can use one of the following teach types:
Teach via receiver control panel (see chapter 8.2.1).
Teach via teach input (see chapter 8.2.2).
Teach via IO-Link interface (IO-Link, see chapter ).
Teach via
Sensor Studio
configuration software (see chapter 12).
8.2.1 Teach via receiver control panel
If blanking areas are configured via the configuration software interface, a teach event is performed that
takes these blanking areas into account (blanking teach or auto blanking, see chapter 4.6).
NOTICE
Conditions for performing a teach!
When teaching without preconfigured blanking areas, the light path must always be completely free.
A teaching error will otherwise occur.
In this case, remove the obstacles and repeat the teach.
If the light path is partially interrupted by structural elements, the permanently interrupted beams can
be suppressed by means of blanking (
auto blanking
function). Interrupted beams are “deactivated” in
this case.
To automatically suppress the affected beams during teaching, configure the number of blanking
areas via the configuration software
Sensor Studio
The configuration can be performed via the IO-Link interface (see chapter ) or via the
Sensor Studio
configuration software (see chapter 12).
You can choose whether the teach values are to be stored permanently or only temporarily (while
the operating voltage is applied). The configuration ex works is for permanent (non-volatile) stor
-
age.
A teach event can be performed both directly from process mode as well as from alignment
mode.
NOTICE
Execute teach after changing the beam mode!
Always perform a teach after changing the beam mode (parallel-/diagonal-/crossed-beam scanning)
as well.
During a blanking teach or auto blanking, an “additional distance” is always added to the beams
detected as interrupted. Safer operation is thereby achieved, e.g., in the case of vibrating guides,
etc., in the “blanked” area.
Optimization of the blanked beams is to be performed via a software interface configuration.
A maximum of four adjacent areas of suppressed beams (blanking areas) can be configured.
